Consumers, when buying health insurance, do not know the exact value of each treatment that they buy coverage for. This leads them to overvalue some treatments and undervalue others. We show that the insurance market cannot correct these mistakes. This causes research labs to overinvest in...

We estimate the effect of binge drinking on accident and emergency attendances, road accidents, arrests, and the number of police officers on duty using a variety of unique data from Britain and a two-sample minimum distance estimation procedure. Our estimates, which reveal sizeable effects of...

Abstract We evaluate the impact of a policing experiment that depenalized the possession of small quantities of cannabis in the London borough of Lambeth, on hospital admissions related to illicit drug use. To do so, we exploit administrative records on individual hospital admissions classified...

A shift in taxes or in government spending (a ”fiscal shock”) at some point in time puts a constraint on the path of taxes and spending in the future, since the government intertemporal budget constraint will eventually have to be met. This simple fact is surprisingly overlooked in analyses...

This Paper computes welfare-maximizing monetary and tax policy feedback rules, in a calibrated dynamic general equilibrium model with sticky prices. The government makes exogenous final good purchases, levies a proportional income tax, and issues nominal one-period bonds. A quadratic...

In the coming decades, the share of people in working age will fall significantly in most developed countries. According to optimal taxation theory, public debts should be reduced before the baby-boom generation retires. I find that if debts are instead maintained at the current levels, welfare...

We investigate the interdependence of fiscal policies, and in particular deficits, in the European Union using an empirical analysis based on real-time fiscal data. There are many potential reasons why fiscal policies could be interdependent, such as direct externalities due to cross-border...

We explore how fiscal consolidations affect private sector confidence, a possible channel for the fiscal transmission that has received particular attention recently as a result of governments embarking on austerity trajectories in the aftermath of the crisis. Panel regressions based on the...

We analyse different forms of international debt mutualisation in a simple framework with a political distortion and (partial) default under adverse economic circumstances. One form is a debt repayment guarantee, which can be "unlimited" or "limited", i.e. only be invoked when the guarantee...

We propose a model-based measure of sovereign credit ratings derived solely from the fiscal position of a country: a forecast of its future debt liabilities, and its potential to use tax policy to repay these. We use this measure to calculate credit ratings for fourteen European countries over...
